孔板流量計安裝對管道的要求：1．孔板流量計安裝時應(yīng)配有一段測量管,至少保持**DN、后5DN的等徑直管段，以提高測量精度。2．在孔板流量計前后若需安裝閥門，比較好選閘閥且在運(yùn)行中全開；調(diào)節(jié)閥則應(yīng)在下游5DN之后的管路中。3．引壓管路的內(nèi)徑與管路長度和介質(zhì)臟污程度有關(guān)，通常在45米以內(nèi)用內(nèi)徑為8-12mm的管子。4．測量液體流量時引壓管水平段應(yīng)在同一水平面內(nèi)。若是在垂直管道上安裝節(jié)流件，引壓短管之間相距一定的距離（垂線方向），這對差壓變送器的零點有影響，應(yīng)通過“零點遷移”來校正。5．引壓管路應(yīng)有牢固的支架托承，兩根取壓管路應(yīng)盡可能互相靠近并遠(yuǎn)離熱源或震動源，測量水蒸汽流量時，應(yīng)用保溫材料一同包扎，必須時（如氣溫0℃以下）加伴熱管防止結(jié)冰。在測量臟污流量時，蘇州金屬轉(zhuǎn)子流量計價格，應(yīng)附設(shè)隔離器或沉降器。6．引壓管路內(nèi)必須始終保持單相流體狀態(tài)。被測流體是氣體時，引壓管路（包括差壓計的壓力腔）內(nèi)全部是氣相；被測流體是液體時，蘇州金屬轉(zhuǎn)子流量計價格，引壓管路內(nèi)全部是液相，不能有氣泡。為此應(yīng)在引壓管路的比較低點裝排水閥或在比較高點裝排氣閥，蘇州金屬轉(zhuǎn)子流量計價格，在新裝或檢修差壓變送器時時應(yīng)特別注意。

超聲流量計優(yōu)點:（1）超聲波流量計是一種非接觸式測量儀表，可用來測量不易接觸、不易觀察的流體流量和大管徑流量。它不會改變流體的流動狀態(tài)，不會產(chǎn)生壓力損失，且便于安裝。（2）可以測量強(qiáng)腐蝕性介質(zhì)和非導(dǎo)電介質(zhì)的流量。（3）超聲波流量計的測量范圍大，管徑范圍從20mm～５m.（4）超聲波流量計可以測量各種液體和污水流量。（5）超聲波流量計測量的體積流量不受被測流體的溫度、壓力、粘度及密度等熱物性參數(shù)的影響?？梢宰龀晒潭ㄊ胶捅銛y式兩種形式。

信號傳輸電纜長度的題目傳感器(即電極)與轉(zhuǎn)換器之間的連接電纜愈短愈好。但有些現(xiàn)場受安裝環(huán)境位置的限制，轉(zhuǎn)換器與傳感器的間隔較遠(yuǎn)，這時要考慮連接電纜的最大長度題目。傳感器與轉(zhuǎn)換器之間的連接電纜的最大長度又由電纜的分布電容和被測流體的電導(dǎo)率決定。實際使用中，當(dāng)被測流體的電導(dǎo)率是在一定的范圍之間，因此就決定了電極與轉(zhuǎn)換器之間電纜的最大長度。當(dāng)電纜長度超過最大長度時，由電纜分布電容引起的負(fù)載效應(yīng)就成了題目。為防止這種情況發(fā)生，使用雙芯兩層屏蔽電纜，由轉(zhuǎn)換器提供低阻抗電壓源使內(nèi)側(cè)屏蔽與芯線得到相同的電壓，以形成屏蔽，即使芯線與屏蔽之間有分布電容存在，但芯線與屏蔽是同電位，則兩者之間就無電暢通流暢過，也無電纜的負(fù)載效應(yīng)存在，因此可延長信號電纜最大長度。另外，還可用特殊信號傳輸電纜延長轉(zhuǎn)換器與傳感器之間的最大長度。
